Description

Technical Field

[0001] The utility model relates to a phosphorus storage device, in particular to a phosphorus storage tank used for buffering phosphorus liquid. Background Art

[0002] When producing phosphorus-containing alloys, phosphorus needs to be added to the molten metal. The conventional practice is to place a phosphorus block directly at the bottom of a crucible, then cover the phosphorus block with metal and other materials, heat the crucible, melt the phosphorus block and metal, and react to produce a phosphorus-containing alloy. To increase the phosphorus content of phosphorus-containing alloys, another method is to directly pass phosphorus liquid into the molten metal, but this method requires the phosphorus liquid to be stored, or to react in a phosphorus pressure tank to produce phosphorus liquid. When injecting phosphorus liquid into the molten metal, it is necessary to adjust the flow rate of the phosphorus liquid and temporarily store the phosphorus liquid, but the current liquid storage tank cannot meet the requirements.
